Call up quote, accepting father's set free (10)
I believe the answer is:
emancipate
'set free' is the definition.
(emancipating is a kind of setting free)
'call up quote accepting father's' is the wordplay.
'call up' becomes 'eman' (I can't explain this - if you can you should give a lot more credence to this answer).
'quote' becomes 'cite' ('cite' can be a synonym of 'quote').
'accepting' indicates putting letters inside.
'father' becomes 'pa' (pa is a kind of father).
'cite' placed around 'pa' is 'cipate'.
'eman'+'cipate'='EMANCIPATE'
Can you help me to learn more?
(Other definitions for emancipate that I've seen before include "release" , "Free from restrictions" , "Free from slavery" , "setting free" , "Liberate" .)
